Carbon Cycle Fourth most abundant element in universe Building block of all living things Main Pathway– in and out of living matter Carbon Cycle
Carbon Cycle- Circulation of carbon through ecosystems Carbon- A non-metallic element found in coal, petroleum and natural gas. Major component of life. Soil Respiration- Carbohydrates are oxidized and returned to the air by soil microorganisms that decompose dead animals Key Terms
Key Terms Continued Atmosphere- layer of gasses Fossil Fuels- Carbon-rich fuel from ancient animals and plants Photosynthesis- Energy (sun)+ Water+ Carbon dioxide Carbohydrates+ Oxygen Cellular Respiration- Glucose+ Oxygen CO2+ H20+ Energy (ATP) Decomposition- breakdown of matter by bacteria and fungi Key Terms Continued
Biological Importance of Carbon All living organisms contain carbon CO2 is found in all living organisms Plants use carbon dioxide and water to form simple sugars (photosynthesis) Biological Importance of Carbon
Ecological Importance of Carbon Carbon is needed for life Carbon dioxide is a greenhouse gas Carbon is necessary for life, but carbon dioxide can be harmful Ecological Importance of Carbon
0.032% in the lithosphere 2 petagrams Amount of Carbon
Carbon in the atmosphere Smallest amount of carbon Approximately 750 petagrams Carbon in the atmosphere
540- 610 gigatons Biosphere
38,00-40,00 metric tons hydrosphere
